Konfiguracja Proguard dla systemu Android Wsparcie v4 22.2.0

Question

Po aktualizacji zależności na kompilacji Gradle Android, aby użyć com.android.support:support-v4:22.2.0 z lokalnego repozytorium dodatków Maven (w ramach SDK), Proguard zaczął rzucać te problemy.

     You may need to add missing library jars or update their versions. 
     If your code works fine without the missing classes, you can suppress 
     the warnings with '-dontwarn' options.

prostu dodając -dontwarn android.support.v4.** rozwiązuje problemu, ale chciałbym się bardziej konkretne/eleganckie rozwiązanie, niż ignorując wszystkie problemy dotyczące pakietu support.v4

Czy ktoś może powiedzieć, jakie zasady powinny być dodawane, więc te classes/@ interfejsy są poprawnie przetwarzane przez Proguard?

Answer 1

Jedynym rozwiązaniem jest to, o czym wspomniałeś, tj. -dontwarn android.support.v4.**. Zostało to faktycznie pobrane z <path-to-android-sdk>/tools/proguard/proguard-android.txt, gdzie jest napisane:

# The support library contains references to newer platform versions. 
# Don't warn about those in case this app is linking against an older 
# platform version. We know about them, and they are safe. 
-dontwarn android.support.** 

Answer 2

Można bezpiecznie ustawić, nie ostrzegaj o klasach biblioteki pomocy technicznej zgodnie z zespołem Android. Możesz to zrobić przez:

## Support library 
-dontwarn android.support.**
